To all whom it may concern:

Be it known-that I, STEPHEN H. Garner, a citizen or the United States, residing at De 'troit, county of \Vayne, State of Michigan,

spread automatically from a wagon. or cart in which it is transported, and is spread by means of appliances that are actuated by the vehicle Wheels acting as traction wheels.

in the drawings :Figure 1, is an elevation of the left side of the vehicle the rear drive and supporting wheel, being removed. Fig. 2, is an elevation of the right side of the vehicle. Fig. 3. is a longitudinalsection. .Fi l. is a plan view. Fig. 5, is a detail of part of the carrier chain and truck. Fig. 6, is a detail oianother part of the-carrier chain. Fig. "I, shows a modified form of link. Fig. 8, is a detail of the sprocket wheel which drives the carrier chain. Fig. 8) is a perspective of the inner end of the huh ot' the rear vehicle wheel, the one at the left end of the rear axle. Fig. 10. is an elemtion oi. the forward Mile and i 5 and t4 inclusive, are perspectives. in 2 and I the axles are sectioned and the rear wheels on the near side are not shown. V.

The two rear wheels serve as traction The two rear wheels of the truck are indicated at 2 and 2. The rear axle 73 turns in bearings and constitutes a shaft to which is keyed a master-wheel 4; the master wheel transmits motion to all the dis-- iriianing parts or the machinery. The distributing part of the machinery consists of a rarrier f, that traverses the bottom of the hos l the upper run of the carrier 5 moves from front to rear and the under-run moves iroin'the rear to front. The carrier is actuated by mechanism. some part of which is shown in Fig. 1. The master wheel i revolves with the axle '73, on which it is mounted, under the actuating influence of the rear truck wheel; each rear wheel has a hub provided with an annular or internally holster.

toothed ratchet face 72. The teeth of the ratchet wheel on the hub engage pawls Tl, pivotally supported on a disk and drive the master wheel at when the truck is drawn forward; should the truck be driven backward the pawls 71 slip over the ratchet teeth without producing a backward motion of the master wheel 4.

The distributing mechanism proper is brought into connection or thrown out oi connection with the master wheel by means of a swinging sprocket chain (3 that is stretched between a sprocket wheel 1%, and a sprocket wheel 9. The sprocket wheel 14 is on an arbor fixed'upon the body 1 of the vehicle. The sprocket wheel 9 is on an arbor carried at the end of a. swinging arm 8; the arm 8is pivoted within a guide that is fixed to the'body of the vehicle and curves outward from the body of .the vehicle and downward with a hanging end which depends belowand in close proximity to the upper run of the rim of the master wheel i. The upper run of the sprocket chain 6 passes through the loop of this guide above the pivot upon which the arnr ,8 swings. The lower" run 10 of the chain (5 passes through the guide below the pivot upon which the arm 8 swings. The arm 8 swings in the plane of the master wheel 4: and the lower run 10 of the chain 6 may be brought .into engagement with the master wheel 4, by swinging the arm? 8 until it assumes the position shown in dotted lines in Fig. 1) This movement of the swinging arm S ma'y be produced from the drivers seat by means of lever and links adapted to that purpose, and which consists of anal-m .13, rigidly secured to the arm 8 intermediate its swinging end and its pivoted end, a link 12, pivotally connected to the arm 18, and pivotally connected to a rock-arm 75, which is journaled on a stud that projects from theside of the vehicle box 1, just at the rear of and slightly below the drivers seat S. A branch 11 of the rock-arm provided with a hand grip 7G and aspring latch 77 is actuated manually; the ratchet of the latch 7 7 en gages in the teeth of a quadrant 78, which serves to hold the parts in a selected position within the range of movement of the parts. On the same shaft with the sprocket wheel 14, and secured to the sprocket wheel 14; to rotate with it, is a second sprocket wheel 15 over which runs a sprocket chain 79 which is stretched between the sprocket wheel 15 and the sprocket wheel 18.. The sprocket wheel 18 is secured to the shaft 17 'of the rotary distributing cylinder carrier on brackets and located at the rear of the vehicle box 1.

The spreader consists of a drum 19 mounted on the shaft 17 and provided with a number of longitudinal ribs 21 in which are inserted teeth 20. The teeth 20 serve as tearing forks to tear apart and to throw backward the manure brought into the path of therotatingforks by the carrier 5.

The carrier 5 is actuated by mechanism which will be best understood by an examination of Fig. 2. Motion is given to .the carrier from the shaft 17, of the rotating drum 19 and this motion is controlled from the drivers seat. The carrier is directly actuated by a wheel 26, to which motion is given by ratchet arms and pawls. In' following the chain of mechanism, through from the shaft 17 tothe wheel 26, there is first mounted upon the shaft 17 a crank 37.

which carries a wrist pin 36; to the wrist pin 36 is secured a pitman 32. The pitman extends along the box 1, to near the middle thereof and is pivoted by pivot 80to the top of a-normally vertical rock-arm 34; the rockarm 34 is j'ournaled on a stud post 35, that extends horizontally from the side of the box 1. On the rock-arm 34 is a sleeve 33 capable of sliding movement along the rock-arm 34; to the sleeve is pivoted a lever 24,the rear end of'which is pinned to the end of a bent lever 25. The bent lever 25 is provided with a number. of holes, into any one of which the pin connecting the lever 25 and the lever 24 may be inserted. The bent lever 25 has pivotally connected to it two links'27 and 28.

The link 28 is pivotally connected to a ratchet lever 30', and the link 27 is pivotally connected to a ratchet. lever 29. I The ratchet levers 29 and 30 are both journaled on a shaft 81 of the wheel 26, the same shaft which carries the sprocket wheels 40 of the carrier. Each of the ratchet arms carries at its free end a pawl held in spring engagement with the wheel 26 and arranged I to impel the wheel26 with a motion to carry 'thereby holding the ratchet lever in its proper position to secure the proper engagement at all times of the pawl 31 with the teeth of the wheel 26. The freeend of the ratchet lever 29 is similarly constructed to -furnish a housing for the pawl 84. The

ratchet levers 29 and 30 are arranged on opposite-sides of the wheel 26 and are in close engagement against the hub thereof.

The end 241 of the lever 24 is pivotally cone ne'cted to a link 38 by which the lever is linked to an angle-lever 23 the angle-lever 23 is, ivoted to a reach rod 22 that reaches to an is pivoted to a hand lever 21 provided with a latch 85 that engages in a' quadrant 39. ;The operation of the hand. lever 21 moves the sleeve 33 along the rock arm 34 and changes the relative position of the fulthe rapidity of the revolution of that wheel under the actuating force of the axle 17.

The'carrier is composed of slats 53'secured to sprocket chains 51 and 52; the sprocket chains run on angle-bar tracks'55 secured to the bottom of the box .1, and the links of the chain or some portion of them arev rovided with anti frictionv rolls' 54. he chains run ',OV8I' a sprocket wheel 40 at the rear end of the box, and-a sprocket wheel 56-at the front end. Only a portion of the sprocket chains are covered by the slats, leaving a part of the run of the chains open; this prevents the accumulation of any foreign matter between the upper and under run, as all such matter dropplng through be tween the slats of the carrier dropsat once to the ground, and is not held in the spacp between the two runs of the carrier; also ,at times when the carrying slats are on the under run, the corners and crevices of the vehicle can be swept out andfcleaned without difliculty. WVhile under most circumstances that type of chain whichis provided with an antifriction roller 54 upon which it may travel along the trackway is preferable be- The under run of the carrier passes over the forward axle and over a guard 57 which extends to the rear of the forwardaxle,

forming a part of the reach of the vehicle, and holding the under-run of the carrier above the space into which. the wheels turn when the vehicle is turned from a direct path in either direction. At the rear end of the ,box 1, arranged to co-act with the spreading \cylinder 19 and the teeth which project from-it is a skeleton end gate 60 pivoted to arms 61, that are pivotally secured to the box 1: A spring 63, secured to the box in front of the pivotal connection between the box andthearm 61, engages with the end gate beneath the point of pivotal connection between the gate and the arm. The spring thus secured to the box and the gate serves to hold the gate in an elevated position when the gate is lifted and to hold it in a lowered position when it is lowered beyondthe point at which the spring passes its condition of greatest tension. The gate and arm upon which it swings are lifted manually by a cord 59 that reaches forward to the drivers seat; its upward and forward movement is stopped by an adjustable stop 67, and its downward and rearward movement is stopped by a stop 68, whichis fashioned as a guide to engage against the upper partof the cross-bar which forms the frame of the skeleton gate, and guides the gate to its proper position with respect to the load underneath it.

The forward truck is of construction especially adapted to permit the passage of the under-run of. the carrier 3 through an opening in the bolster, or between the two members which constitute the upper and the lower part of the bolster; the construction is shown in Fig. 16).

llpon the axle 90 rest. castings 91 to which are bolted two members 92 and 93 of a double axle cap; upon the cap rests the lower member 94- of the fifth wheel; the upper member 95 of the fifth wheel rests on the lower member and is secured to the lower cross member 96 of a bolster between which lower member 96 and the upper member 97 is a space 98. through which the lower-run of the chain travels. 97 of the bolster are secured together by bracket castings 99 that'are provided with suitable flanges 100 and 101, to engage against the end and along the upper face of the lower member, and is also provided with a step bearing 102, on which the upper memher 97 of the bolster rests; the brapket itself is bolted to the longitudinal beam ,1 framepiece 10?), which constitutes the lower part of the side of the vehicle box. The track rails 55 are. secured to the upper member 97 of the bolster.

The guard 57 is secured to the lower member 96 on the upper side thereof and braced to the lower side and the guard alsofas- 'tened to a hanging cross-bar llldthat crosses under the vehicle at the rear of the truck'and is supported by hangers 105 and brace 106, thus constituting a compound reach comprising the; side member-s ot the wagon box, and tneguard 57, and the cross-bar 101 with its hangers.
